Description:

Calpain-1 (μ-Calpain) is a calcium activated neutral cysteine protease. It is a heterodimer of a Catalytic 80 kDa subunit and a 30 kDa subunit, which requires 50 μM Ca2+ for half-maximal activity in vitro. Its participation in events such as cell division, signal transduction, and long term potentiation has been suggested. Calpains have also been proposed to play a role in various pathological processes associated with altered metabolism and altered calcium homeostasis.
